Author: bz Date: Wed May 18 14:18:03 2016 New Revision: 300147 URL: https://svnweb.freebsd.org/changeset/base/300147 Log: Make compile without INET or without IP support in the kernel by hiding variables and lro function calls behind approriate #ifdefs. Also move the #includes for "opt_*" to the place where they should be.
